Incorrect Employees Output on a Page with SiteOrigin Builder

Hello!
At first, I would like to say thanks for such a great theme.

Today I’ve catched a strange bug with employees widget.
On a main page of my website I have combination of various widgets. Accidently the section (or row in terms of SiteOrigin) with employees started to show wrong elements.

I’ve checked everything in my custom post types and taxonomies and after all I’ve explored that if the employees widget is placed below Post Carousel widget the first one becomes broken. It shows some random elements.

Can you help me? Maybe I should also contact the developers of Siteorigin Widgets Bundle?

Here is that page (it’s in russian): https://mooc.tsu.ru/ru/moocs/
